Vehicle Security
Guard Against Theft
Your new vehicle has many features
to help prevent theft of the vehicle,
its equipment and contents. But
these anti-theft features depend
upon you to work.
The time to be most on guard is
when leaving the vehicle:
.Park in a lighted spot when
you can.
. Turn the engine control switch to
"LOCK" and remove the key.
This locks the switch and the
steering controls. The selector
lever is not locked.
. Keep items that may appear to
be of value out of sight and
locked up when possible.
. Fully close all windows and lock
all doors.
Exterior Mirrors
Mirrors
Sit in the correct driving position
with the seat adjusted properly.
Then, check each mirror to ensure
that a proper view of the rear and
sides of the vehicle are provided.
Make adjustments and clean mirrors
if necessary.
Outside Rearview Mirrors
After properly adjusting your seat for
proper driving position, adjust the
mirrors so that they provide
adequate views for checking the
rear and the sides of the vehicle.
Adjust the outside rearview mirrors
by hand before vehicle operation.
This helps you determine the
location of objects seen in the
mirror. If the outside mirror fogs up,
warm up the outside rearview
mirror's face to defog.
See Heated Mirrors 034.

Driving and Operating 141
Never Stop the Engine While
Driving
{Warning
Do not move the engine control
switch away from the "ON"
position while the vehicle is being
driven.
If the engine stops while the
vehicle is moving, the brake
booster does not work, and the
brakes would not work properly.
The engine could also be
damaged.
Stopping the engine while driving
would be extremely dangerous
because the power steering
would stop working, making the
steering wheel extremely hard
to turn.
Stopping the engine while driving
would be extremely dangerous
because the warning lights,(Continued)
Warning (Continued)
indicator lights and other
electrical circuitry would
completely stop working.
Placing the engine control switch
in the "LOCK" position while
driving would be extremely
dangerous because the key could
come out, causing the steering
wheel to lock so that you could
not turn it.
You and others could be seriously
injured.
Avoid Unnecessary Idling of
the Engine
If the engine idles too long, the
engine coolant temperature will fall
below the operating range. Low
engine operating temperature
causes several conditions that are
harmful to engine operation and life.
Incomplete combustion of fuel in an
engine that is not fully warmed-up
causes crankcase dilution and
forms lacquer and gummy deposits on valves, pistons, and rings. It also
causes rapid accumulation of
sludge within the engine.
Driving at Night
Nighttime driving is more dangerous
than daytime driving because the
field of view is narrower. Keep your
speed down, and maintain an ample
headway distance.
Metallic Plinking Sound from
the Muffler
Immediately after stopping the
engine, you may hear a metallic
plinking sound from the muffler. This
sound occurs as the muffler cools
down and contracts. It does not
indicate an abnormality or
breakdown.
